knowledge representation
KR
The subfield of {artificial intelligence} concerned with
designing and using systems for storing knowledge - {facts}
and {rules} about some subject.
A body of formally represented knowledge is based on a
{conceptualisation} - an {abstract} view of the world that we
wish to represent. In order to manipulate this knowledge we
must specify how the abstract conceptualisation is represented
as a {concrete} data structure. An {ontology} is an explicit
specification of a conceptualisation.
